POUNClNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 602,978, dated April 26, 1898. Application filed December 17, 1896. Renewed October 1, 1897. serial No. 653,746. (No model.)

To a whom it may concern.-

Be it known that I, GEORGE E. CLARKE, a citizen of the United States, residing at Montell,Uvalde county,TeXas, have invented certain new and useful Improvements in Pouncing-Machines,of which the followingis a specification.

This invention relates generally to a machine for pouncing the crownsof hats, and specifically to certain improvements on the machine embodied in my application, Serial No. 577,650, filed February 1, 1896, and now pending.

The features of improvement will be hereinafter described and carefully distinguished from the old features of the machine as shown in the said pending application.

In the accompanying drawings an embodiment of the improved machine is illustrated.

Figure 1 is a side elevation of the machine as it appears at the termination of the pouncing operation, the base of the pedestal being in section. As the operator stands at the right in Fig. 1 and facing the machine this View shows the left-hand side thereof. Fig. 2 is a front elevation of the upper part of the machine, on a larger scale than Fig. 1, showing the parts in the position they occupy at the beginning of the pouncing operation; and Fig. 3 is a side elevation as seen from the right in Fig. 2. These views, Figs. 2 and 3, include the novel features of this invention. Fig. 4 is a face view of the pouncing-pad detached.

I will first briefly explain the general-construction and operation of the machine, as more fully set forth in the above-mentioned pending application, and then describe the novel features.

On a hollow pedestal or frame 1 is mounted a head 2, which is carried by an upright hollow shaft 3 in the pedestal, and during the pouncin g operation said head is turned slowly around through about a quarter-revolution. \Vhen the operation is completed, the drix ing mechanism is automatically thrown out of gear, (as here shown by shifting a belt,) and the head may be then unlocked or disconnected from its shaft and turned back again tothe startingpoint. ThehatI-Itobepounced is fitted on a block clutched to a horizontallymounted shaft in the head, and this shaft is driven, through intermediate mechanism, from an upright shaft 4, extending through the hollow shaft 3. The hat is thus rotated slowly about its axis at the same time that it is carried about with the head 2. The main driving-shaft 5 in the base of the frame or pedestal drives the shafts 3 and 4 through any suitable gearing. In Fig. 1 this consists of a peculiar differential gear, which is fully described in the said pending application. As the hat H is rotated it is pounced by a pouncing-pad 6, carried by an arm '7 and held up to the hat by a spring in a casing 8 on the pedestal or frame. The pad 6 receives motion in a closed curved path through the medium of a counter-shaft 9 in the frame, driven from the main shaft 5. On the end of the shaft 9 is a crank 9 to which the lower end of the arm 7 is coupled, and the said arm has a sliding bearing at 10 in a frame 11, hinged to the pedestal 1. All of this is clearly illustrated and described in the said pendiugapplication.

I will now describe with more particularity the means employed for giving to the hat what is called an oval motion about its axis, promising that as a hat-crown is elliptic or oval in cross-section andthe pad is held up to it by a yielding spring-pressure it is desirable that the center of rotation of the hat shall be moved to and fro during the rotation toward and from the pouncing-pad in order to compensate for the elliptical form of the hat-crown, and thus avoid variable pressure of the pad on the hat during its ro tation.

On the upper end of the shaft 4 is fixed a bevel-wheel 12, which gears with a bevel-pinion 12 fixed on a counter-shaft 13, mounted in bearings in the head 2 perpendicular to the shaft 4:- On the shaft 13 is fixed a gearwheel 14, which gears with a similar wheel 14 of twice: its size, fixed on the shaft 15, which carries the hat H and which is rotatively mounted in a bearing-piece 16, mounted loosely on the shaft 13, at its foot, and adapted to swing or oscillate about the axis of said shaft 13 as a center. The shaft 15 is substantially parallel with the shaft 13, and the oscillation of the bearing-piece 16 does crum-bolt 20, the construction being such that the lever may be fulcrumed on the arm 18 at any point along the slot. An arm or connecting-rod 21 is coupled at and to the upper arm of the lever 19, and in the other end it has an eye which loosely embracesthe 1 boss of the wheel 1 Another connectingrod '22 is coupled at one end to. the lower arm of the lever 19, and in the other end has an eye which embraces aneccentric 23, formed on the boss of thewheel 14.

The elfect of the above-described mechan ism is to rotate the shaft and at the same time impart to it, through the eccentric 23,

- rocking lever19, and rods'21 and 22, a motion tation of the hat.

it is feasible to do itwhile themachine is in L1 toward andfrom the pouncing-pad, this os cillation being effected twice during each to I The extent of this oscilla- 1 tion may be varied at will by loosening the fulcrum-bolt 20 and moving the lever 19 up I or downiu order to vary the length of itsi arms,.and theconstruction enables thisto be done quickly and conveniently without disturbing or dismantling themachine. Indeed operation.

forming of the eccentric 23integral with the boss of the wheell, the mounting of the bearing-piece 16 directly on the counter-shaft 13,

and other minor details ofthe construction are merely matters of choice and need not be strictly followed in carrying out the invention in practice.

In order that the pouncing-pad may adjust itself the better to the surface of the hat, es-

pecially in passing about an abrupt curve where the side of the hat-crown joins the top thereof, the pad is swiveled in the line of its longitudinal axis, as will now be described.

The pad 6 is made by preference of rubber and faced with fine sandpaper suitable for pouncin g. The pad proper is provided with metal end pieces 6 to which it is removably secured by a screw and thumb-nut 6, so that it may be readily removed and replaced. On each end piece 6 in line with the longitudinal axis of the pad, is a collared journal 6", which finds a bearing in a suitable pad-support 7 on the arm 7. The journals 6 permit the pad to turn freely about its longitudinal axis when the exigencies of the case, as stated above, require it to do so. To avoid marking the hat in the pouncing, it is desirable that the pad shall be free to adapt itself to the surface to be pounced at all times.

When the pouncing operation is completed, the motion of the machine is stopped by the automatic shifting of the driving-belt, and at the same time the pad is pushed quickly away from the hat and back to the position seen in Fig. 1, where it is held until the pounced hat is removed and replaced by another and the head 2 turned back to the starting-point.

In the before-mentioned pending applica tion the belt-shifting device is shown, the

same comprising the elbow-lever24, coupled by alink 25 to the shiftingrspring 2,6, and the toggle 27, which holds the lever 24: when set.

It also showsthe means for breaking the knuckle of the toggle upward at the termina-- tion of the pouncing operation, such means comprising a pin 28, carried by the head 2,

adapted to act through a suitablelever29 to break the toggle. A lever30, fulcrumed out-he pedestal back of the toggle, is coupled at its lower end by a link 30 to the hinged frame 11, and at its upper end it has a pin 30 which engages the lever 24. Fig. 3 shows the position of the parts at the moment he I fore the knuckle of the toggle is broken up.- ward. When this takes place,the quick movement of theupper end of the lever 24: swings the lever 30 over and pushes the frame 11 back. This frame carries back the pouncing-pad, the arm of the latter being hinged at the point where it iscoupled tothe crank 9.

In Fig. 3 I have only shown a part of the teeth on the wheels 14: and 14%, and in Fig. 2 a part of the head 2 is represented in section, as is also the boss of the wheel let and the eccentric 23.

claim'the driving mechanism shown in Fig. 1 at the base of the machine, nor do I limit myself thereto. Any known form of mechanism may be employed for driving the several shafts 3, 4, 5, and 9.
